Odds are that the GTX 580 is a lot less limited by ROP/bandwidth than the 670/680 is.
 
It will be interesting to see how the 660 & 660 ti stacks up against the 7850 & 7870, especially given how the AMD cards both come with 2 GB VRAM and 256-bit memory interface standard. I'm glad NVIDIA is finally going to release a challenger to AMD's Pitcairn-based cards. More competition ultimately benefits the consumer (too bad the same can't be said about Intel's dominance in pure x86 performance vs AMD).
 
I'm starting to get the feeling I bought the wrong GPU... Ah well, at least I only spent $460 on it and it's not like it's suddenly start to crash and artifact at stock clocks.

I love AMD.

More on topic: I'm really hoping that the 660 has just 960 cores and the 660ti 1152, I may then be able to sleep at night.

Yea say goodbye to your sleep.
 
Thanks, really reassuring...

It's 1:52AM where I am, BTW.

At least the prices on the 7870 my fall so I can consider XFire and I guess if the 660ti is faster, the 7870 won't exactly lose performance overnight.

In all seriousness, that's not a smart choice to base where your money goes. But you are the master of your own universe, the bus width on my 690 may be smaller then the 384 on my old 580s, but its a leap forward in terms of efficiency, overclocking, and heat produced. That's kind of what I look for.
u just trollin bro?

obviously im not going to go buy a 280

but since this is GDDR5 the memory interface is less important, but it will eventually be available at a higher amount

which I will wait for
 
Hmm... Interesting. Although, with games like Crysis 2 and C3, BF3, and other new games coming out. The hi-res textures really take a hit on VRAM. I would imagine with the new generation of cards coming out, 2GB of Vram needs to be standard. I'm already maxed out my Vram with Crysis 2 with hi-res textures on a single 1080p screen...maxes my 580.
Oh well. It's a mid-range card for 2012...Can't expect the absolute top end out of everything...

Not possible: 192 bits = 128 + 64 (or if you prefer 128 *1.5).

You have to find a 1.5 coefficient somewhere if you've got a 192 bits bus.

1.5 GB = 1536 MB = Ok
3 GB = Ok

1536MB + 768MB = 2304 MB ~2.3 GB "could" be possible (but not used in reality: 1.5GB or 3GB, nothing between those 2 values).
 
Used 570's on ebay for $200, and Newegg has a MSI 7850 for $209 after MIR...... bench on anandtech shows those to be pretty similar. Decisions decisions.... money been burning a hole in my pocket for 2 months now waiting for the stupid 660 or TI to drop...
 
If I was looking for a card in the $200-$300 range, the 1.5 GB VRAM would almost be a deal-breaker for me. Seriously. If you enjoy high-resolution textures, 2 GB GDDR5 minimum is a must at 1080p.

With 1.5 GB, you can forget about properly running 1440p, 1600p, or multi-monitor setups, especially with the 192-bit memory interface. It is not at all future-proof. Future games that are optimized for PC hardware and running the latest graphics engines (Frostbite 2, Unreal 4.0) will quickly be bottlenecked by the lack or VRAM/bandwidth.

Luckily consoles have held back graphics progress for all this time since they are limited to 512 MB VRAM for the XBOX 360, 256 MB VRAM + 256 MB system RAM for the PS3, so 1 GB VRAM has been sufficient up to now. This situation will rapidly change once the next generation consoles are released next year, and developers will adjust accordingly. VRAM will only become more and more important in the future, so stock up now.
